This presentation will consider the ways that modern genetics and lipidomics are beginning to increase our understanding of specific lipid disorders that bear on human disease, ranging from life-threatening conditions of infancy through severe coronary heart disease of young adulthood, to indolent disorders of middle- and old-age. The case will be made for replacing the traditional, but now 45-year-old, Fredrickson and Lees essentially phenotypic classification of hyperlipidae...

Background: Heterozygous germline AIP mutations can lead to young-onset invasive GH-secreting adenomas. There are no data available to explain the proliferative and invasive nature of AIP-mutation positive somatotrophinomas.Methods: Cell viability (MTS assay), invasion (single cell fluorescence invasion assay) and migration assays (Boyden chambers) were used to further characterise the phenotype of AIP-silenced GH3 cells. Affymetrix gen...

: AIP mutation-positive familial isolated pituitary adenoma is commonly diagnosed in young patients who have a poor prognosis due to large, treatment-resistant tumours. Microarray analysis carried out on AIP knockdown pituitary (GH3) cells and control cells, identified CDC42 as one of the genes that was up-regulated by loss of AIP protein. This small Rho GTPase activates MAPK signalling, suggesting it may contribute to the proliferative phenotype of AIP knock...
